FRANKLIN, NEW YORK.

. Be known that I, WILLIAM a citizen of the United States,'and resident of New York city, in the county of New Yorkand State ofNew York, have, invented certainfnew and useful Improvements in Wrenches, of which the following is a specification. j

This invention has for its object to provide, in a sliding jaw tool such as a wrench or pipe cutter, improved means for efiecting the automatic sliding movement of the jaws from the swingingof a handle; in which the construction and assemblage of the parts will be simple and eiiicient; and in which the construction of the parts will give a maximum amount of strength to withstand a great amount of pressure and strain from hand and continuous use.

A further object of the invention is to provide in the said form of a tool, a construction in which the sliding jaw member is pivotally connected with a swinging handle by a link that is pivoted at its ends respectively to the two saidmembers by being merely inserted laterally into sockets in such members, and retained in operative position causing the swinging of the handle to reciprocate the jaw member, by the opposed walls of a slotted portion of thebody of the wrench.

V A further object of the invention is to provide in the form of wrench above set .forth, wherein a sliding jaw member is operated from a swinging handle by" a connecting link, a form of abutment wall onthe body memberadapted to engage a portion of the handle, for thepurpose of receiving the thrust imparted to the link when the jaw member is closed underpressure on a nut or other object, wherein the strain On the pivot of the swinging handle will be removed or In the accompanying drawing illustrating embodiments of my invention: Figure 1 shows the tool in elevatiomin open position.

Fig. 2 shows the device closed "on a nut, being a section of the line 22 as indicated in Figfi l'. Fig, 3 shows the body member in elevation. Fig, 4 shows the body member in end View. Fig. 5 shows a piece connecting;

the side walls of the slot in'the body member. Fig. 6 shows a block secured in'the slot 1n the body member, forming an abutment wall for the handle. Fig. 7 shows inelevation' Specification of Letters Patent.

thejaw member. Fig. 8 is an end elevat 1on of the aw member. Fig. 9 shows the llnk. I Fig. 10 shows the device as set forth in the aforesaid views, with cutting wheels or disks for use as a pipe cutter; and Fig. .11 1s an end view of the device asset forth in Fig. 2, with the addition of cutting blades 'jaw'member and also the handle and the link are each as shown a single integral structure; while the body member is composed of a slotted plate having at two opposite portions a small plate or block connecting the opposite walls of the slot and permanently secured in such position, forming a unitary structure without movable parts initself.

The body member 12 comprises a main portion 16 having an extension 17 at one corner that constitutes one of the jaws of the device; while the said main portion 16 is provided with a slot made throughoutthe Patented June 8,1915.

interior of the main portion, thereby forming opposed walls 18 and 19- that are connected integrally only by the jaw 17, as indicated in Figs. 3 and 4:. These opposed walls18 and 19 are connected at the two lowerycorners blocks 20 and 21 respectively, that may be secured in placeby rivets or other means.

The jaw member 13 is shown as composed of a shank portion 22'having a jaw portion a 23 projecting from the upper edge at one end of the shank, and of a width correspondingto thejaw 17 of the body member; while the shank portion 22 is of less width,

being of a thickness to slide in the slot 24: formed by the'twowalls'1 8 and 19 of the bodymember. j V The upper edge 25 of theshank 22 -will engage the wall of the slot 24 formed by the jaw, portion '17 while the opposite edge; 26

27 of the block 20, inthe slot 24 in the bot 'ofthe shank 22 will be guided by the edge that containing the jaw 23 has an extension or lug 28 on the lower side, and this portion'is .guided by the wall 29 formed by the piece 21 that is secured in the slot 21' in-tlie body. By these means the jaw member 21 is slidable in the body member to move its jaw portion 23 to and" from the jaw 17 of] the body member;

The handle 14 is shown as having its end ,inserted'in the slot 24 and is movably connected .withthe. body member, preferably by means of a pin passing through the two ,walls 18 and 19 of the body-member, and,

through an aperture .31 in'thehandle, by which means the handle is pivoted on the bodymember.

The, sliding jaw member is connected with the -pivoted handle member by means of a l nk, that is pivoted at its ends respectively to-these two members, whereby the swinging of .the handle fromv the position i i-which the parts are shown in Fig. 1, to the position indicated in Fig. 2, will cause the jaw member 13 to slide on the body member, and

bring the jaw 23 of the jaw member nearer to the jaw 17 of the body member. I In the constructionillustrated the link 15 is'shown' as havinga head 33 at one end of circular shape, and also a circular head 34 shown as provided with a slot 35 that is of at .the otherfiend." Thejaw member 13'is circular shape, and located at the portion of V 1 the lower edge26 that joins the lug 28, this slot being somewhat larger than a semi-circle, and of a size to havethehead 34 inserted therein by a movement lateral to: the two members; and the link being of thesame thickness as the shank 22 of the jaw member,'to fit in the slot, 24 of the body member,

the walls 18 and 19 of the body member will :serve to hold the link in operative connection withthe jaw members; itbeingpermit- .tedto swing a certain distance as will be un- .dcrstood' by comparing-Figs. 1 and 2, and

the head, cannot be withdrawn from "the socket by any pull orthrust'in the direction oi. the plane of the flatlink'.

I The handle 14- '5: provided withalsocket 36 formed of a circular curve to receive the; head 33 on the link 15 as shown' in Fig. 2,

that will b e 'retainedin such position after its lateral'insertiomby the walls 18 and 19 .arejrequired; these three members,; the

handle the link and the jawimember are first connected by inserting the two-heads in their; proper sockets, and then these mem of the slotted-portion 2410f the body" member.

It will be seenathat the link is piv-' V otally-connected with the jaw member and. with the handle by integral means, and no additional members such as pinsorscrews here are inserted intothe slot 2410f the body member before the blocks'f20 and 21'. (or

.cutter. v 5 r VVhen this tool isfiapplied toapipe or Trod, and the handle swung to closethe jaws, V 7 the three cutterswill grip the pipe, and as the devic egis swung 'to} move it around the sition: and then the'pivot pin 30' is inserted to secure the handle in properpositiomand thesetwo blocks are secured in their proper position,whereupon the device is assembled in finished condition ready for use.

It will be understood by reference to Fig.

from its position of Fig. 1 to that of Fig. 2 in which it is closed on anutn, and continued pressure will cause the toolto turnthe nut on a'bolt b in; the direction of thearrow on f the nut; and it will beper'ceivedthat the movement imparted --to the shank 22 of the jaw member, through the 11111115, willjbe by a thrust on the link, and not a pull; but the swinging of the handle in the opposite direction will cause a pull or tension on the link, which movement will open the jaws. But

if it is desired-totum thenut in the opposite direction, then the wrench is reversed or the'end of the handle 14.is provided'w'ith a' curved edge 40 concentricwithits axis of movement; and the block 20 is provided with a curved wall 41 also concentric to the axis of the pivot 30, and "practically coincidentwith theourved wall 40; andwhen the'handle is swung Ito theclosed position indicated in Fig.2 and pressure still applied, the described thrust on the link :15 ,will cause these curved walls 40 and 41 to engage and "receive the thrust that would. tend to shift the handle member on the bodymember, by either shearing the pivot .pin, or enlarging its hole 31 inthe handle end portion. If desired: the pivot pm can have a slight amount of lateral'movement,

its'hole 31 in the handle to permitthe said walls 40and 41 to approach andrecede, so-thatthe handle will not bind in The construction of a tool" with sliding jaws as has been described, is readily appli'cableto any form of a tool wherein, two 7 members carrying operating devices are brought to engage opposed portions of an ;object;-and in FigQlO a-construction identical with that described is .shown, in whichv aJ ELW member 17 is providedwlth a pair of cutters-42 and 43, while'thejj'g 2351 providedwith asingle cutter 44, thatifare locatedisimilar, to the cutters on i '2, that pressure on the handle '14; in the direction'fof the arrow, will shift the jaw 23 pipe, the pressure on the handle will con stantly move the cutter 44 toward the op- I posed cutters 42 and 43, and as fast as the cutters sink into the pipe or rod, the pressure on thehandle will advance them, causing them to feed in under a continuous pressure.

In Fig. 11 another form of tool is shown in which the jaws 17 and 23" are provided with cutting blades 45 and 46 respectively, that will obviously be caused to approach when closed on an object, and pressure on the handle tending to swing the tool around the object, will cause a continuous pressure on the two blades that will feed them into the article as fast as a channel is formed jaw, said block having a flat upper face- Gopies of this patent may be obtained for constituting a guiding surface, a jaw carrying slide mounted to move transversely of said head and disposed between said guiding surfaces, a handle, means for pivoting said handle to said head upon the same side of said head as that uponwhich the slide lies, one edge of said handle above said pivot being provided with a socket, and the opposite edge of said handle above said pivot being formed upon the arc of a circle concentric with said pivot, that portion of the block adjacent said arcuate surface of the handle conforming to the curcontact therewith throughout, a pressure link having rounded ends, one of which is- 'vature of the surface and lying in close 7 pressure link, the contact of the curved surface of the handle with the correspondingly shaped surface of the block serving to relieve the pivot of strain Where the jaws come to a position of rest in grasping an object.
